I doubt that she doesn't want to help herself. I haven't seen the programme but there aren't many people who are happy being so large that it causes serious health problems. Food is a mood altering drug and people can get addicted to it. I should know - I have definitely been addicted and am still fighting against it now even having reached goal. I suspect that many of us here also suffer from this. Addictions are very hard to fight, even when physcological help is available. They can be beaten though, but judging someone who has tried and tried and is now trying again isn't very helpful. Does it matter if it takes 10 times to solve the problem as long as it gets solved?
There is a real social problem with food addiction. It is looked down on by society and it's acceptable to look at someone who is larger and call them names or say that it's their own fault. This is so pervasive that the people themselves who suffer from food addiction often say the same things about themselves. This is not hellpful for anyone and certainly doesn't help people accept that this is a serious problem which needs to be given attention without judgement. Do we judge the sports enthusiast for the money they cost the NHS when they break their leg playing rugby? They may well be addicted to the endorphine rush after exercising - but we judge their behaviour as 'good' and people's food addiction behaviour as 'bad'. When we judge other people I think we need to stand back and look at ourselves and why we're making that judgement. It says far more about us then it does about them.
